China is the largest iron- and steelmaking slag producer in the world, and intensive efforts have been made during last …

The stacked slag is taken and fed by the forklift and conveyed using the belt conveyor. The slag is transported by the elevator into the vertical mill for grinding. The slag powder is then collected by the powder separator and dried using a hot blast stove. The dried slag powder is transported into the vertical mill for regrinding, after which ...

China is the largest producer and consumer of calcium carbide in the world. The calcium carbide industry is an indispensable industry to support the basic life of people. The huge production capacity of calcium carbide is accompanied by a large number of solid waste carbide slag. Due to the immature treatment technology of carbide slag, a large …

Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing". Although there is no limit set, the downsizing process over 3 mm is considered as "crushing ...

The preparation of sand and gravel aggregates from tunnel slag involves crushing, screening, and sand making, with the main process being "more crushing and less grinding, replacing grinding with crushing, and combining crushing and grinding". The characteristics of the processing material directly affect the design of the sand and …

When the wet-grinding steel slag content is 10%, the compressive strength of the specimen (constraint) after 28 days of curing is the highest, reaching 68.5 MPa, which is 9.3% higher than that of the free curing specimen, and the impermeability is also the best. ... China). RSS and WSS were obtained by crushing and mechanical grinding. ISO ...

The gasification fine slag was treated by airflow crushing and classification, and the enrichment effect of residual carbon in Product II was the most obvious. When the grinding gas pressure was set to 0.5 MPa, the low carbon product with fixed carbon content of 4.99% and yield of 19.86% could be obtained.

The raw material production of cement plant can be classified into four steps: crushing, grinding, mixing and homogenizing. Crushing: the limestone and other materials are crushed into small pieces by cement crusher, such as hammer crusher, cone crusher, jaw crusher, impact crusher, etc. Mixing: according to the requirement of clinker, compound ...

The effect of TiO2 on the crushing strength for high-Cr V-Ti magnetite pellets was studied in this paper. On one hand, the crushing strength obviously decreased with the increasing TiO2 contents.
